BOWLING MACHINE TOTALIZER ATTORNEY Patented Mar. 25, 1952 UNITED STATES PATENT OFFICE BOWLING MACHINE 'ro'ramzsa Application January 2, 1947, Serial No. 719,869 30 Claims. (c1. 273-43) This invention relates to a bowling totalizing and scoring device which totalizes and scores the results of one or more players from the beginning to the end of each game, whether each player is bowling individually or as a member of opposing teams, and whether each player is bowling on one or two alleys during the playing of a game.

The mechanism is 50 arranged that any number of players up to, say two teams of five players each, can bowl as is customary in league play, on two alleys, and each individual players score, and also the team scores, are progressively totalized and scored or made visible on a suitable scoreboard or annunciator panel forming a part of the machine or used in conjunction therewith. In this manner each player sees on the scoreboard exactly what he would see on a score chart if his score was being kept by a scorekeeper.

Heretofore in the game of bowling it has been customary to use scoring charts or blank forms provided by proprietors or operators of bowling alleys for scorekeeping. It is generally customary for either the bowler himself or a person designated for the purpose to keep score. After each frame is played, the frame score is written in the appropriate place in the box or part of the score chart corresponding to the particular frame adjacent the name of each player. If, for instance, a strike or a spare is made on the first or second ball, respectively, of a frame, a symbol wellknown in scoring the game is placed in the upper right-hand corner of the box representing that frame to indicate the results of the pin fall by a particular ball in the case of a strike, or two balls in the case of a spare. In the case of a strike, two balls must be rolled before appropriate scores in preceding boxes can beentered. In case of a spare, scoring is delayed until the next or first ball of the next frame is rolled; whereas in the case of two normal balls knocking down less than ten pins, the frame score can immediately be entered and the play to that point totalized.

As far as is known, we are unaware of any device which can be used in connection with full size normal bowling alleys employing full size conventional, free bowling pins such as ten pins, duck pins or candle pins, etc., which automatically registers pin fall from frame to frame as the game progresses and records and totalizes each score of one or'more players, individually or in team play. Accordingly, the solution of this problem, which is evidenced by the present invention rep-resents an important advance in the art. It makes it possible for'each player .to direct his Mass., assignors to full attention to his bowling and improving his score, because he is not required after the completion of each frame to stop and enter his score, or record the results of a ball thrown in the case of a strike or spare, yet each player substantially, immediately after each frame is completed, can see the results of his and his competitors play to and including the frame last completed. Furthermore, it is not necessary to require the services of another player or an intermediary to tabulate the results of the play as the game progresses.

Our invention also solves the problem of providing an automatic bowling totalizing and scoring device which can be used in scoring and totalizing the play on a single bowling alley using a bowling pin setting machine, or scoring and totalizing the play of several bowlers on two bowling alleys using two independently operated bowling pin setting machines having means for sending selective impulses to the scoring and totalizing device which automatically totalizes and scores the in-turn frame by frame play of the several bowlers bowling either on one alley or on first one and then the other in turn during the frame to frame play of complete games.

Our invention also makes possible a'minimum of discussions and argument arising in connection with entries on the score'ch-arts since the proper result is automatically set up in our machine with positive accuracy at all times regardless of the number of players within the limits of the machine. For purposes of illustration we have shown mechanism capable of caring for up to five players per side or fewer as the case may be. If desired, however, in the totalizer illustrated up to five bowlers could use a single alley and all scores could be properly tabulated and totalized.

The totalizing mechanism, which forms our invention, is so constituted that it will indicate a spare, a strike, or two spares or strikes, or any combination thereof in succession or be operated by normal, less than ten pin, pin fall frames. The totalizer records each mark made by each player, and memorizes the occurrence thereof so that although the scoreboard does not indicate the exact numerical score until the appropriate ball of the next frame or next two frames is or are rolled depending upon whether a spare or a strike is made, they are properly taken into account in the scoring so that each player looking at the scoreboard, and in particular at his own score panel, can see his numerical score, and also the mark or marks credited to him, though not yet totalized. For example: if a player starts a game with two successive strikes, his score is zero until he bowls the next ball. Hence, at the end of the second frame the totalizer scoreboard will read zero for this particular player, but two strikes will be indicated in that players individual annunciator or scoring panel. After the next ball is thrown, this being the first ball of the third frame in the case assumed, the proper score for this players first frame will be immediately indicated because of the fact that he has then rolled the two balls required by the rules for completing the scoring of the first strike.

A similar situation exists in the case of a spare. For example: if a spare is made on the second ball of the first frame, the score indicated for the first frame will be zero until after the first ball of the second frame has been rolled after i which the totalizing mechanism sets up the proper score for the first frame. In the examples given above, reference to the first, second, or third frame is merely exemplary since the principle of scoringobtainsthroughout the entire play except in the case of a spare or a strike in the tenth frame, which will be. described. hereinafter. The sametotalizing and Scoring relationship. obtains for all players as each player bowls in turn in playing hisgame.

The totalizer andscoring. mechanism which constitutes our invention is designed primarily for use with bowling pinsetting machines, and especially with machines which. have, means for indicating pin fall and progress of play from frame to frame to the end of each game. The

invention, however, is not to be considered limitedonly. tov use with bowling pin setting machines since, it can also. be used in conjunction with manually operatedor pincontrolled mechanisms for operating thetotalizing and scoring mechanism to obtainthe desired results. When used with an automatic bowling pin setting machine, our invention is especially suitable and well adapted for conjoint operation with a machine of the general type shown in Rundell patent, No. 2,388,707, issued November 13, 1945, and copending Broekhuysen application, Serial No. 627,605, filed;November9,,1945, for Bowling Pin Setting Machinanow Patent 2,559,274, granted July 3;,19511. Whenour invention is employed witha machine ofthegtype shown in the Broekhuysen patent, the electric control mechanism oi the howlingpin,settingmachine is interconnected with ,the electric circuit and control of our totalizing, and; scoring mechanism in order to eiiect the; desired; registering, scoring and totalizing or; the entireplay'for-one or more players, or opposed-teamstconsisting of from one to five plav rsnai ide.

The; conjoint operation of the pin setter and totalizin mechanism isso constituted that after each balljofj a frame is, thrown by a player, whether, itbe open individual competition or team play, duringthe subsequent operation of the bowling. pin setting machine impulses are sent from the bowling pin setting machine to ournovel bowling pin totalizer indicating the result of. each ball thrown or pin fall caused. thereby, whereupon the totalizer takes into con-- sideration the pin fall, or whether or not the first or last ball of a frame has been thrown and there is automatically set into operation the coacting mechanism for registering both normal pinfall, strikes and spares, and special cases such as fouls, dead balls,.etc. In the latter, which can be termed specialcases, manual circuit operating elements are actuated-in order to con trol=the operationof the totalizer mechanism and thereby obtain the proper results. In this way it can be seen that accurate results are obtained at all times as the play of the game progresses from the beginning to the end inasmuch as the operation of the automatic totalizing mechanism is coordinated with that of the automatic bowling pin setting machine from which it receives its impulses.

While reference is made particularly to the use of our invention in connection with bowling pin setting machines, especially automatic bowling pin setting machines, it is apparent that it can also be used on bowling alleys in which semiautomatic pin spotters are employed, or where only manual spotting is used. In these latter cases, it is necessary to have an actuating means which will send the proper impulses to the totalizer representing the pin fall for each ball of a frame so that the resultof the plays of the game can be progressively recorded and tabulated by the totalizer and set up on the score board.

It is an object of our invention, therefore, to provide a totalizer for use with bowling alleys: which solves the problem of accurately totalizing and registering bowling scores.

- on the other alley.

It is also an object of: our invention to provide a totalizer and score indicating device which automatically and progressively computes and records the bowling score of one. or more bowlers bowling on a single alley or adjacent bowling alleys.

It is a further object of our invention to provide a totalizer and score indicating device which automatically and progressively computes and.

each ball of a frame causes the actuation of" our novel bowling totalizer to indicate the score-of' one or more players on one or two bowling alleys during the progressive play on one or two alleys with which the bowling totalizer is associated.

It is a further object of 'our-inventionto provide a bowling totalizer which can be used-in connection with a single alley or two alleys, and

which will record pin fall as eaclrframe o-fa game is played whether it be the result ofa single player bowling on a single alley-or a plurality of players bowling against each other in open play or in team play. In'the case'of team play, individual team scores are also automatically-totalized during the play untiliat the end of eachgame the complete team score aswell as individual scores are automatically and accurately;

computed and made visible;

The invention is further characterized'by the provision of an automatic bowling totalizer which automatically and accurately sets up and progressively computes bowling scores in a foolproof manner thereby eliminating inaccuracies which arise in human score keeping;

It is a further object of our invention to provide a bowling totalizer preferably for use with automatic bowling pin setting machines which computes individual and/or team scores on one or two alleys and which takes into consideration all of the rules prescribed. by the American Bowling Congress, especially in connection with fouls, deadballs, and other special cases which can readily be compensated for in order that an accurate score can be set up and computed.

The invention also consists in the provision of novel score indicating mechanism which indicates the progressive play of the game of one or more players, and totalizes each individual players game; and in the case of team play totalizes and indicates the final score of each team.

The invention is also characterized by the provision of a novel scoreboard associated with and forming a part of our totalizer and scoring mechanism which is provided with a plurality of panels adapted to indicate the score, frame of play, occurrences of marks (strikes and spares) and also the final score of each player.

The invention also consists in the provision of a scoreboard which contains separate team panels including separate panels for individual players on each team. Each players panel is provided with mechanisms associated with and forming part of our novel bowling totalizing and scoring mechanism for indicating the individual score, frame of play, occurrence of marks (strikes and spares), and the final score. In addition there is also included in each team panel scoring mechanism for tabulating and indicating each teams score.

Other objects of our invention will be set forth in the following description and drawings which illustrate preferred embodiments thereof, it beme understood that the above statement of the objects of our invention is intended generally to explain .the same without limiting it in any manner.

In the accompanying drawings which illustrate a preferred embodiment of the invention and form a part of this specification, and in which like characters of reference indicate the same or lik parts:

Figures 1 to 7, inclusive, show a partial view of a preferred wiring diagram and mechanism employed for totalizing and scoring progressively as the game proceeds and also indicating the final scoreof each bowling game whether it be for one or more players in direct competition or in team play; c

Figure 8 shows the arrangement of Figures 1 to 7, inclusive, in proper associated relationship to form a complete diagram;

Figure 9 is a view showing a preferred form of a preferred scoreboard which forms a part of the invention, and the manner in which it may be used'with one or two bowling pin spotting machines; and.

Figure 10 shows a modified resetting switch suitable for use in resetting in single alley operation.

The preferred embodiment illustrated in the drawings shows our novel bowling and totalizing device used in connection with an automatic bowling pin spotting machine of, the type shown in the above referred to Broekhuysenpatent. In-

formation obtained by the bowling pin setting machine as the result of pin fall after each ball of a frame is thrown and after each frame is completed is impulsed by selective mechanism shown in Figures 1-7 inclusive to the totalizer and converted into a totalized score for each player, and if the players are bowling as teams, team score mechanisms are operated to totalize and score the results of each team.

Our device is so constituted that each individual score indicator will at all times after each frame is rolled show exactly what would be visible to a bowler on a standard score sheet as the frame 7 by frame play progresses. In addition, each player s panel of the totalizer will show a mark, such asa spare, a strike or two strikes if such marks have been made by a player, but have not yet been taken into account for scoring. For example, if a player starts the game with two successive strikes, his score is zero until he bowls the first ball of the next or third frame. Hence, at the end of the second frame, the totalizer will read zero but two strikes will be indicated in the proper indicating space of that particular bowlers panel or scoring and totalizing unit.

The game is normally divided into ten frames, each having a predetermined number of balls. In the case of tenpins, two balls are allowed per frame. In the case of a strike, all pins are knocked down by the first ball; the frame ends with the throwing of the strike ball.

If a spare or a strike is made in the tenth or last frame of a game, one or two bonus balls are allowed respectively. Mechanism is provided for automatically taking each bonus ball into consideration and computing the proper score. Our mechanism conforms to customary rules of play in that as soon as each bowler completes normal bowling in the tenth frame he immediately rolls off the bonus balls alotted him as the results of the type of mark he has made in the- The scoreboard may take any desired form provided it contains sufficient mechanism and indicating devices to satisfy the purposes of our invention.

A preferred embodiment of the scoreboard or annunciator designated 20 is shown in Figure 9. Scoreboard 20 is constituted of two team panels 22, 24 which may be formed either integrally or in two separate juxtaposed units. As shown in Figure 9, panels 22 and 24 are formed in one integral unit. Panel 22 is provided with five player panels or units numbered A, B, C, D and E, although more or less can be furnished if desired. Panel 24 is likewise provided with live player panels or units designated F, G, H, I and J. Panel 22 is provided with a team scoring unit 26 for one team; panel 24 is provided with a team scoring unit or panel 28 for the opposing team.

Since each of the player panels or units is identical, it .is considered suificient to describe but one in detail. In player panel A, for example, there is provided an indicator 39 which indicates the, frame of the game at any instant. As shown in Figure 9, .the sixth frame has ben completed by player A. 32 designates the mark indicator on player panel A, and as shown in Figure 9, makes it apparent that two strikes have been rolled in succession so that the scoring indicator 34 has not yet set up the final score resulting fromthe rolling, of the last ball of frame No. 6.

7 For illustrative purposes assumed individual scores, and team scores are indicated in Figure 9. Assumed marks (strikes and spares) are also shown at 32.

Generally team play in league or openplay competition takes place on two side-by-side alleys. Our bowling totalizing and scoring mechanism, as illustrated herein, preferably is employed in conjunction with two automatic bowling pin setting machines mounted on two adjoining alleys Al and A2, although its use is not'so limited and it can be used on one alley with equally satisfactory results. In team play, one team bowls on one alley, say alley Al, while the other team bowls on alley A2. In order to indicate which alley the members of ateam arebowling on at a particular time, an alley indicator 36 is provided in each of the'player panels. As shown in indicator 36 for player C, the right-hand alley A2 is being bowled by members of the first team; at the same time, as shown in player panel H, the left-hand alley Al is being bowled by members of the second team. The several indicating means of each of the player panels described hereinabove are preferably electrically operated. The construction and operation of the operating mechanisms is described hereinafter.

A bowling pin setting machine of the type shown in the above mentioned Broekhuysen patent is provided with a pin spotting and respotting device, designated generally it having one respotter unit II for each pin, or ten triangularly arranged units H in the case of ten pins usually used. Each unit is provided with a switch 320 (Figure 6). As described in the above mentioned patent, after each ball of a frame is rolled, the spotter-respotter device it) is moved by suitable mechanism (not shown) to a position adjacent the alley with which the machine is associated to test for the presence or absence of standing pins whereupon if any pins are standing, certain of the switches 32% are closed. As shown in Figure 9 two machines 2 and 4 are mounted in the kickbacks of two side by side alleys Al' and A2. Switches 320 in units ii are connected by cables [4 to the electric control mechanism of the pin spotting machines 2" and 4.

The result of the movement of a spotter-respotter device If! to pin testing position after each ball of a frame is rolled, causes impulsesto be sent to the totalizing mechanism in order to selectively operate selected mechanisms and thereby effect the totalizing of each individual bowlers game, and also each team score. For

example, with either machine 2 or i, if after the first ball of a frame is rolled on either alley Al or A2, one or more pins remain standing, the particular switch or switches 320 corresponding to the position or positions of the pin or pins standing on the alley is or are moved to circuit closing positions, and lights (see Figure 6) corresponding to these pins are energized and glow. In the interest of brevity it is assumed that alley Al is in use, hence the signal lights in the annunciator used with machine 2'are energized. At the same time, each relay 326 in machine 2 (Figure 6) corresponding to a particular standing pin is pulled in and the circuit through corresponding contacts 325d is broken. The effect of this operation is to indicate that certain pins remain.

standing, say for example, Nos. '7 and 9. As is customary in scoring a game, no score is placed on the score chart until the last ball of the frame is rolled, except in the case where spares or strikes are completed, and the aggregate score til 8 is entered to complete the score in the frames in which such marks were made. In a two ball per frame game, the impulses received from the respotter devices l i cause the operation of a particular player totalizing unit to score the pin fall for that frame only after the second ball is rolled, when less than ten pins are knocked down.

It will be remembered, however, that in normal bowling scoring, no score is indicated for pin fall on the first ball of a frame, except in the case where a spare has been made in the immediately preceding frame, and pin fall for the first ball is added to ten, and the ten plus the number of pins on the first ball is added to the prior score to complete the score through the frame in which the spare was made. In a simple two ball frame where less than ten pins are knocked down, it is only after the second ball is rolled that impulses resulting from the contact 326d remaining closed cause the totalizer unit 35 for the particular bowler who has just completed his frame to operate and totalize the score to and including that frame. The score showing in each players panel will be exactly the same as it would be in a conventional chart now used.

In a similar manner, if all pins are knocked down by the first ball of a frame and a strike is made, none of the ten switches 32% is closed. However, light ST of machine 2 is energized. A strike impulse is sent to the selected totalizer and scorer so that the proper strike memory circuit is operated, and the strike scored properly after all balls allowed for that strike have been rolled as the play of the game progresses from frame to frame.

If all pins are knocked down by the second ball of a frame, none of the switches 320 of machine 2 is closed. However, spare light SP is energized and an impulse is transmitted to the spare memory circuit of the totalizing and scoring mechanism, so that after the first ballof the next frame is rolled the proper score is reg istered and made visible in aparticular players panel and also his teams score if team play is occurring.

Figures 1 to 7, inclusive, arranged as indicated in Figure 8, disclose the preferred complete electric circuit and operating mechanism of the entire totalizing and scoring device, and its-connections for use with two automatic bowling pin setting machines 2 and 4. In the interest of simplifying the drawings, details of necessary electrical connections with only bowling pin spotting machine 2 have been shown. For the same reason only two complete player operating and totalizing units have been shown. The remaining player actuating and totalizing units and connections with machine 4 are identical in construction and operation, and are connected in the circuit disclosed in Figures 1 to '7 in the same manner. The two player units disclosed are for players on opposing teams; player A is on one team; player F is on the opposing team.

Bowling pin spotting machine 2 is connected in operative relationship with the totalizing and scoring mechanism (as shown in Figure 3 by means of connections 522, 566, 5IBB, 5i9, 504, 503, 562, 523, 520, MBA, 56?, 595 and 5|! referred. to hereinafter. In a similar manner pin spotting machine 4 (Figure 5) is connected in operating relationship with the totalizing and scoring mechanism through connections 5l'la, 505a, 507a, 518D, 520a, 523a, 502a, 503a, 504a, 519a, 5IB'C, 506a and 522a.

Alley sequence wheels Scoreboard 20 preferably is located above and centrally of the two side by side alleys AI and All. For alley AI there is provided an alley sequence wheel unit W0, which controls the operation of the totalizer in response to impulses transmitted from bowling pin spotting machine 2 on alley AI. A second alley sequence wheel unit WT controls the operation of the totalizer in accordance with impulses transmitted from the bowling pin spotting machine 4 on alley A2.

Since both sequence wheel units W and WT are the same in construction and operation (see Figures 3 and 5), only one is described in detail. Unit W0 is provided with a suitable motor 50, such as a gear reduction motor capable of driving shaft 52 on which are mounted two spaced cams 98 and I00. Cam I00 is provided with a high portion I02 and a low portion I04 tracked by a switch operating arm I06 opening and closing switches WI9 and W20 during the operation of motor 50, as described hereinafter.

Cam 98 is provided with a high or switch operating portion 93 which during the rotation of cam 98 engages switch operating arms WI-WIIB, and W23-W25, inclusive, to momentarily make or break control circuits of the totalizing and scoring mechanism. In the description hereinafter, when mention is made of either wheel W0 or WT rotating, it is to be understood that this includes cams 98 and I00.

In Figures 17, two individual player scoring units 34 are shown connected in proper operative relationship in the operating circuit. In the form of totalizer and scoring device illustrated, ten separate units 30, 32, 34 and 36 are required, each of which is connected in the operating circuit in the same manner as units 30, 32, 34 and 36, designating players A and F on opposing teams. Inclusion of each of the units 30, 32, 34 and 36 in detail showing in the Figures 1-7, in-

clusive, has, therefore, been omitted in order to' simplify the drawings, and prevent unnecessary repetition of showing.

have proved satisfactory in use. It is only necessary that each five players team counter be capable of totalizingthe maximum possible score of 1500. a

Player advancing mechanisms In order to operate each individual player unit (which includes frame indicator 30, mark indicator 32, scoring unit or counter 34 and alley indicator 36) it is necessary after each player has bowled, whether in individual competition or in team play, thatthe totalizer mechanism be set automatically for properly computing the score of the next player who bowls and also indicating the alley, spares or strikes, and frame number. If two teams are playing, that part of the totalizer mechanism and operating circuits which is provided for each team score is actuated selectively to effect the necessary and proper re- H0 (I I2) consists of a plurality of discs or sections II4-I2'I each having a center conducting arm mounted on shaft I30, each center conducting arm being separated from the others by suitable insulation I32. Also mounted on shaft I30 are cams I34, I36 on which run switch operating arms I 38, I40, respectively. A ratchet '44 also secured to shaft I 30 and engaged by pawl 48 of step relay ILL is operated at the proper time to turn shaft I30 one step to advance the center arms of each of the discs from one position to the next. That is, when player A, say, completes a frame and bowler B of the same team is next to bowl, the information transmitted by impulses from bowling pin setting machine *2 on alley Al to the totalizer causes the energization of relay ILL and shaft I30 turns clockwise, as viewed in Figure 2, 4 and '7, one step. In the case of player advancing mechanism II2, shaft I3I is turned counterclockwise after each player completes a frame.

It will be noted that each player advancing mechanism is provided with ten active positions and two inactive positions, twelve in all, thirty degrees apart. The active positions correspond to the ten players representing two teams. The inactive positions occur at the points where each team completes its play on one alley, and shifts to the other. In player advancing mechanism IIII, the twelve oclock position designated is an inactive position. Reading clockwise, in mechanism II 0, are positions A, B, C, D and E with the second inactive position at the six oclock position designated X Then follow positions F, G, H, I and J all of which positions correspond to the ten players, five on a side. Player advancing mechanism H2 is also provided with similar player positions and two inactive positions, except that the positions of team one players A-E, are out of phase with the positions of the same team members on mechanism IIO. This arrangement allows five players A-E, inclusive, to bowl on alley AI while bowlers F-J, inclusive, are bowling on alley A2. When each team com- I pletes a given frame, the center arms of discs II4-I2'I move to the inactive positions described above and danger of improper totalizing and scoring is prevented. When, however, each team, that is when players on team I on alley AI and players on team II on alley A2, begin a new frame, step relays ILL and 2LL are actuated and the proper operation of the player and team totalizing mechanism is effected. As described hereinafter, properly controlled electric impulses operate step relays ILL and 2LL to advance the center arms of discs II4-I2'I, from inactive positions to positions representing players A and F, respectively, after each team has shifted from one alley to the other.

The player advancing mechanisms are designed preferably for teams of five players. However, it is quite possible to totalize and score the play of ten bowlers A-J, inclusive. in individual Disc [2! operates the first strike signal.

competition. In this case the team score counter can either be deactivated or the score appearing thereon can be disregarded. If less than ten persons desire to bowl, and use the totalizing and scoring mechanism, adjustment can be made which will enable them to bowl as teams of less than five members, or as individuals. These conditions will be described in detail hereinafter.

In Figures 2, 4 and 7 each disc El i-I21, inelusive, is shown diagrammatically as provided with a conducting arm having a contact and arranged to turn progressively through 30 increments and engage contacts labelled A-E in quadrants I and 2, and F-J in quadrants 3 and 4 of player advancing mechanism fill, and F-J in quadrants I and 2, and A-E in quadrants 3 and 4 in the case of advancing mechanism H2.

In the same manner, when bowler F completes a frame, shaft [3i is turned counterclockwise to advance the contact points on discs N l-i2! shown as conducting contact bearing arms, from player position F to player position G. The totalizer mechanism is then set awaiting results obtained by players B and G on their respective alleys. Similar stepwise rotation of shafts 138 and I3! takes place after each bowler concludes a frame. When all bowlers on a side have completed their play and change alleys, the center arms of discs lid-i2! of each player advancing mechanism I H) and H2 turn to inactive six (X or twelve (X) oclock positions, as described. An additional pulse is then sent to relays ILL and 2LL which causes the center arms of discs 1 l4-! 2? to rotate one more step which advances them so that their single contact points engage contacts at stations F and A, respectively, awaiting the beginning of play of the next frame, each team exchanging alleys from frame to frame as the game proceeds.

In the totalizer control illustrated, the fourteen discs designated lid-I21, in each of the player advancing mechanisms provide means for selectively operating all related mechanisms to totalize and score each individual p-layers game and team score. Discs l i i, l 45 and H5 control the operation of the units, tens and hundreds indicators of each of the players score totalizing units of which there are ten. However, as noted above, only two complete totalizing units, representing opposing players A and F, are shown. Disc Ill operates a release relay in each player unit memory circuit for spares and second strikes, i. e., a strike immediately following a first strike. Discs H8 and I I9 operate mark indicator signals for spares and second strikes, respectively. Disc I29 opcrates the first strike memory switch release relay. Disc I22 operates the delayed count relay which makes it possible to accurately totalize a players score after the first ball after a spare, and the second ball after a strike for the prior frame in which the spare or strike was made. Disc I23 operates what is termed a tenth frame relay because it functions in accordance with results obtained by the last ball rolled in the tenth frame. This action may result in a strike (in which case two bonus balls are delivered) or a spare (in which case one bonus ball is delivered) or less than ten pins knocked down for the two balls of the tenth frame. Disc I24 actuates a selected frame counter to show which frame of a game a particular player has completed. Disc I25 operates selected alley indicator signals to show on which alley a particular player is bowling. Disc l2? operates *Qomit switches, and disc I26 operates the waiting stations or inactive positions relay. The waiting station control makes it impossible for bowlers to cause inaccurate totalizing and scoring in the event that players on one team on one alley finish their frames before the other team on the other alley complete their play in the corresponding frame as the game progresses from frame to frame to'the end of the game.

Pin spotting machine control for totalizing and scoring mechanism interconnections As mentioned hereinabove our novel totalizing and scoring mechanism is especially adapted for use with one or two automatic pin spotting machines. In the embodiment selected for purposes of illustration, the totalizer is shown in use with two automatic pin spotting machines 2 and 4. In Figure 6 there is disclosed a portion of the control mechanism employed in the bowling pin spotting machine illustrated in the above referred to Broekhuysen patent. Only that part of this mechanism is illustrated which will make possible the transmittal of impulses needed to selectively operate the totalizing and scoring mechanism constituting the present invention. This is because the pin spotter controls form no specific part of our invention and hence further description and showing thereof are omitted in the interest of brevity.

For the same reasons, in Figures 1 to 7 there are only shown in detail one circuit and its associated mechanism employed in one bowling pin Broekhuysen patent there is provided a control cam shaft 255 on which are mounted a plurality of circuit making and breaking cams. The cams, which are used in connection with our invention for transmitting the desired information to our totalizing and scoring mechanism and for operating mechanisms are cams 428, 362 and 406. An additional cam 600, not forming a part of the bowling pinspotting machine control mechanism, is also employed.

As described in the Broekhuysen patent, the timing of cam shaft 255 is such that it makes one half revolution for each ball of a frame rolled or one complete revolution for each normal two ball frame. By means of the above mentioned cams and the circuit making and breaking mechanism operated thereby, and the operation of the bowling pin spotting tables I!) which move to and A, from either alley A1 or alley A2, as the case may be, and effect a closing of the switches 320 (Figure 6) when engaged by the head ends of standing pins, which thereby selectively operate relays 326, suflicient information is transmitted from each machine to the alley sequence wheels W0, WT It: operate the totalizer and effect the desired resu Pinsetter information The pin spotter recognizes the following events: (1) A ball is delivered;

(2) This ball .is a strike;

(3) This ball completes a spare;

(4) This ball completes a frame; and

.(5) Any pins that are lgnocked down.

The operation of the pin spotter which causes the movement of table 10 to and from alleys A1 and A2 after the rolling of each ball, therefore, closesthe switches corresponding to the above noted items as follows:

(1) When a ball is delivered;

(2) When a strike is made;

(3) When a spare is made;

(4) When a frame is completed; and

(5) When relays 326 are operated to cause the operation of alley sequence wheels WO or WT (or both when two bowling pin spotting machines are in simultaneous use) to effect the necessary rotation of earns 93 and 100 to operate switches W! to W20 and W23W25, inclusive, and operate switches, relays, ratchets, indicators, lights, etc. to give the desired operation as described above or as will be described hereinafter.

Example of totaliser scoring The chart shown hereinbelow illustrates what .the totalizer will indicate in an assumed game.

For purposes of simplifying the description and drawings, the scoring of one single player rolling a single game involving all possible strike, spare and non-mark combinations incident to the rolling of this game will be described. It is to be understood that when more than one player is bowling, say two five-player teams on two alleys, the scoring of each individual player will follow exactly the same sequence and involve the same mechanical and electrical operations as set forth in the play of a single bowler. The scoring example in the chart is chosen arbitrarily except that it is to be noted every scoring possibility, of which there are twelve, which can occur in an actual game, has been included. The totalizer will indicate at the end of each frame exactly the same information as appears in each frame portion of the score sheet shown in the chart.

In the game under consideration it is, therefore, assumed that there is only one bowler, say player A and that he remains on one alley, say alley A1. Under such circumstances, the player switch ratchet 44 does not move. Hence, no reference is made to the action caused by contacts W20and W23 of alley sequence wheel W0 since it is these contacts which advance the player switch. In the following description of the scoring of an assumed game where no mention is made to specific contacts being opened or closed by cam 98 of an alley sequence wheel, the opening or closing of such contacts has no efiect. A separate description appearing hereinafter will be given of the operation of the player switch.

Conditions before the first hall is delivered The first-ball light 424 of the bowling pin spotting machine control mechanism (Figure 6) is energized through the circuit from the power line through contact 3622; through contact 350 through contact 428a through light 424 to ground. The second-ball light 426 (Figure 6) is not energized because there is no completed circuit through it since it is connected to the open terminal 4281) (also the open contact of 350 the latter being opened and closed at the proper time in the operation of bowling pin spotting mechanism 2 by means of a step relay 350 shown in part in Figure 6. Thus, there is no power on line 502 and hence relay SB is not energized. (This is seen by starting at 426 (Figure 6) and tracing to the junction of contact 42% and line 502 which goes to coil SB of Figure 3.)

Play and totalizing and scoring of assumed game (one bowler) In the chart shown there is indicated as assembly of the scoring of the assumed game. In the play shown in the chart all possible bowling combinations are indicated. In the pins-down column are shown the results obtained by first and second balls, except on strikes where only one entry appears.

Ball '1, Frame 1 Eight pins fall; 'say 7 and 9 remain standing. The ball drops into the pit of the alley (not shown.) This closes switch 300 which is connected by wire 30! to a delayed closing relay 302 (Figure 6). This allows a few seconds, say three for example, before the ball and pin handling mechanism of the pin spotting machine, say machine 2, begins operating. Switch 300 is also connected by wire 505 to relay KK (Figure 3) which in turn is connected by closed switch (1124 to ground. Thus, as soon as the ball arrives in the pit relay K is energized. This closes contact KKl, and opens contacts KKZ and KK3 (Figure 3). Contact KKI is connected to normally closed contact WI 8 on sequence wheel W0. This explains how the frame-duration relay K is energized and remains energized until the end of each frame.

When the predetermined time has elapsed after the ball arrives in the pit, delayed action relay 302 is activated and closes contact 304 (Figure 6). This completes a circuit from power through 304 through normally closed contact 3481) of the pin spotting machine control through wire 522 through normally closed contacts SSI (Figure 3) through contact Zt3 (Figure 7) through wire 52!, through switch 305, through contact 402a, through relay 308 to ground (Figure 6). As explained in the above mentioned Broekhuysen patent, the energizing of relay 308 starts the pin setter sequence. The pin spotting machine control causes normally open contact 3020!. to be closed by cam 362 mounted on shaft 255 (Figure 6), which supplies power directly through switch 305 and contact 402a to relay 308 and holds relay 308 energized until the end-of the cycle (even afterthe ball is delivered from the pit which opens switch 300). As soon as cam 362 starts'to rotate power is removed from contact 36% and the first ball light 424 goes out. Cam 406 also on shaft 255 now operates, opening contact 406Rb and closing 400Ra momentarily. The reason for this will be described hereinafter. Then 406Ra opens and 406Rb remains closed.

Table I0 is constructed and operated as shown in the above referred to Broekhuysen patent.

Nos. 7 and 9 close two of the contacts 320 (Fig- This completes the circuit from the power line through switch 362a through switch 320 through relay coil 326 through normally closed contact 4I6d to ground (Figure 6). Since this energizes two relays 326 corresponding to pin positions '7 and 9, contacts 326D of these two relays 326 close. This completes the circuit from the power line through 406Rb through the normally closed push-button 602 through contact 32612 through relay 326 through contact 4I6d to ground. This holds relay 326 energized even after the standing pins are released from the respotting units I I and reset in on or off-spot position on the alley.

When the pin spotter sequence started, say three seconds after the ball arrived in the pit, and shaft 255 began to rotate, cam 600 thereon was turned. This closes contact 600a and completes the circuit from the power line through contact 600a through the now closed contacts 326a through the proper signal lamps through normally closed contact AIM to ground. This, in the assumed case, energizes lights Nos. '7 and 9 showing that pins 7 and 9 are standing. These lights remain energized until a short time, about two seconds, before the pin spotter cycle is completed at which time cam 600 has rotated (approximately 180) so that contact 600a has opened and the lights are extinguished.

Since two of the contacts 3260 are closed, there is a completed circuit from the power line through 362a through 326c through wire 504 through the normally closed contact DFZ'through coil of relay NM to ground. Thus relay NM is energized, indicating a non-mark (a mark has not been made) Since two relays 326 are energized, as explained above, this opens the two contacts 326d corresponding to standing pins Nos. 7 and 9 but leaves closed contacts 326d corresponding to pins 1, 2, 3, 4, 5, 6, 8 and 10 which (as will be seen below) allows us to score these fallen pins as a result of rolling the first ball of the first frame.

Shortly aften the standing pins '7 and 9 have energized relays 326, cam 406 turns into position to close contact 406L, which completes a circuit from ground (Figure 6) through wire 506 to normally closed switch db! (Figure 3) through the motor 50 to the power side of the line. Motor 50 starts and rotates cams 98 and I00 of sequence wheel WO mounted on shaft 52. Gem 406 is so shaped that contact 406L remains closed until cam I00 of WO has rotated far enough so that cam portion I02 closes contact WI9 and opens contact W26. Then 406L opens. However, W0

* continues to rotate because the circuit through motor 50 is completed from ground through WIS through motor 50 to the power side of the line (Figure '3). Wheel W0 continues to rotate until it has made one (or sometimes two) revo1u tlons, as will be explained below.

In .recapitulating the action thus far, when the ball arrives in the pit, the closing of switch 300 results in the energization of frame duration re- .lay K and about three seconds later time delay relay 362 which starts the pinspotter sequence.-

Table I0 then moves down and any standing pins close selected contacts 320 which energize the corresponding relays 326 which are thus capable of giving the totalizer the information as to how many pins have fallen. Then, due to the rotation of shaft 255, cam 406 closes contact 406L which supplies an impulse which starts motor 50 and wheel WO rotating.

It can be seen how the scoring is effected or prevented until the proper time by following the sequence of events during the operation of motor 50 and as cams 98 and I00 of alley sequence wheel W0 or WT rotate. It is to be noted that relay NM is energized but that relay SB is not. It is also pointed out that, any relays which have not already been specifically said to be energized are in their unexcited state and the contacts are as pictured in Figures l-7, inclusive.

As cam 98 of wheel W0 rotates, high portion 99 closes WI and opens WI8 momentarily (Figure 3). Power is applied to contact WI which is connected to the open contact UI and to the open contact YY2 (Figure 3). Hence, this circuit is not completed. Power is removed from WIS but this power went to the open contact VI and hence this circuit is not disturbed. WI 8 is also connected to the now closed contact KKI and it might be thought that the power is hence removed from relay KK. However, the circuit from the power line through the now closed contact NM9 through the normally closed contact SE8 through the now closed contact KKI through coil KK through contact 11124 to ground keeps coil KK energized even though WI8 is opened.

Continued rotation of cam 98 causes high portion 99 to close W2 momentarily. Power is applied to W2 which is connected through closed contact FF2 to the now open contact NMI. Hence, this circuit is not completed. W2 is connected to open contact YY2 and to open contact U2. Hence, no circuit is completed.

Due to the continued rotation of cam 98, W3 is closed momentarily. Power is applied to W3 which is connected through now closed contact NMZ (Figure 3) through wire 5I'I through closed contact 326d corresponding to pin I (Figure 6) through wire 50'! through the now closed contact NM3 (Figure 3). At this point designated P, the circuit branches. One branch goes through closed contact PPI to open contact SB2 and hence is not completed. The other branch goes through closed contact FF3 to open contact U3 and hence is not completed. Thus by either path there is an open circuit from point P on. Thus W3 has no effect.

Next cam '98 of WO closes W4 Power is applied to W4 which through line 5I6 through closed contact 326d corresponding to pin 2 (Figure 6) through wire 50'! through the now closed contact NM3 (Figure 3) to point P. As noted above, the circuit is open beyond P. Thus W5 has no eifect.

Cam 98 of WO closes contact W4 momentarily. Power is applied to W5 which is connected through line 5I5, through closed contact 326d corresponding to pin 3 (Figure 6) through wire 50'! through the now closed contact NM3 (Figure 3) to point P. As noted above the circuit is open beyond P. Thus W5 has no eifect.

It will be evident, therefore, that as indicated above, rotating cam 98 of alley sequence wheel W0 for alley A1, and bowling pin spotting machine 2 also closes contacts W6, W1, W8, W9. WIO, WI I and WI2 in turn momentarily. In the same manner, as set forth with respect to conmomentarily. is connected tacts W4 and W5, since the circuit in which each of these contacts is located is open beyond P, these momentarily closed contacts have no effect in totalizing and scoring pin fall for this ball, which is exactly what would take place in manual scoring. In the case of W9 and VII I, the circuits are open also at contacts 326d since the relays 326 are energized by the standing pins 7 and 9.

Continued rotation of shaft 52 causes cam 98 to close contact WI3 momentarily. Power is applied to WI3 which is connected by wire l6 through disc I H of the player advancing mechanism H (since player A is bowling on alley A1-Figure 3) through coil R to ground. Thus relay R is momentarily energized and contact RI momentarily opens. This, however, has no effect, since there was no completed circuit through contact RI even before cam 93 closed contact WI3. Thus power is applied through contact RI to either open contact TI or open contact ZI (Figure 4). Thus the closing of contact W I3 at this time has no effect.

In the continued clockwise rotation of cam 98, contact WM is next closed momentarily. Power is applied to WM which is connected by wire A! through disc II9 of the player advancing mechanism (Figure 4) to open contact Y2. There is another branch of the circuit from contact WI 4 through normally closed contact FF5 (Figure 3) to now open contact NM i. Thus the closing of contact WI 4 at this time has no effect on the scoring and totalizing operations.

Power is applied to contact Wl5 which is connected by conductor A3 through disc 26 of the player advancing mechanism (Figure 4) through coil RR to ground. Thus relay RR is momentarily energized and contact RBI momentarily opens. This, however, has no effect on totalizing and scoring operations since there was no completed circuit through contact RRI even before cam 98 closed contact WI.5. Thus power is applied through contact RR! to open contact YI (Figure 4). Thus the closing of contact WI5 has no effect at this time.

Contact WIG is next closed momentarily by cam 68. Power is applied to contact Wl6 which is connected through normally closed contact FF l to the now open contact NM5. Thus the closing of contact WI6 at this time has no effect in totalizing and scoring.

Cam 98 next closes contact WI'I momentarily. Power is applied to contact WI'I which is connected to either the open contact SR6 or the now open contact NMI (Figure 3). Thus closing of contact WI'I has no effect.

Cam 98 next closes contact W23 and opens contact W24 momentarily. Power is applied to contact W23 which is connected to open contact SB? and now open contact NM8. Thus, closing of contact W23 has no effect. When contact W24 is opened, power is removed from contact W24 but this has no effect since contact W24 was connected to the normally open contact NNI (Figure 3).

Cam 98 next opens contact W25 momentarily. Power is removed from contact W25 which is connected to open contact SBI. Hence this has no eifect. Contact W25 is also connected to open contacts FFI and V5 and hence opening contact W25 has no effect.

Cams 98 and I06 on W0 now have finished one complete revolution so that contact WIS opens and contact W20 closes. The opening of contact WI 9 removes power from the motor 50 (Figure 3) and hence the wheel W0 comes to rest. During the operation of wheel W0, the pin spotter mechanism has also been operating, and hence shaft 255 of the control shown in Figure 6 is turning so that at the proper time before the end of the pin spotter cycle, rotation of shaft 255 causes cam 660 to open contact 666a and lights I and 9 go out.

When pinspotter 2 completes its cycle shaft 255 has made one-half a revolution. Therefore, cam 362 has made half a revolution and power indicators receives pulses) on scoreboard 20 in I the player panel corresponding to player A. Also, the frame is not complete, frame counter 30 is not advanced. The memory relays, described more in detail hereinafter are not set. Relays KK, NM and SB are energized, and two relays 326 are also energized.

Ball 2, frame 1 One more pin, say No. 7 falls (only No. 9 pin remains standing).

The ball arrives in the pit closing switch 306. On the first ball of a frame this energizes relay KK as described above. However, on the second ball it has no effect since KK is already energized. A short time later, say three seconds, the pin spotter cycle begins and shaft 255 begins to rotate. As soon as cam 362 on shaft 255 starts to move the second ball light goes out. However, relay SB remains energized since there is a completed circuit from the power line through closed contact W25 through now closed contact SBI through coil SB, through closed contact dbl to ground. Cam 486 on shaft 255 now operates and opens contact 456R!) momentarily, thereby deenergizing all the pin relays 326. This is evident from the fact that relays 326 were maintained energized by the closed circuit from the power line through contact 4U6Rb through the closed contact 602 through all contacts 32Gb which were closed and their coils 326 through the closed contact 4I6d to ground. Thus, when 496R?) is momentarily opened, the power is removed and relays 325 are deenergized and contacts 3261) open.

A. short time later, as described hereinabove, table It! descends and a standing pin (No. 9) closes its corresponding contact 320. 'This completes the circuit from the power line through contact 362a corresponding to the position of switch 326 through pin No. 9, relay coil 326 through normally closed contact H611 to ground (Figure 6). Since this energizes relay 326 then contact 3261) closes again. This completes the circuit from the power line through 456Rb (which due to the rotation of shaft 255 is now again closed) through 602 through No. 9 pin relay contact 3261) and through its coil 326 through contact 4I6d to ground. This holds No. 9 pin relay 326 energized even after No. 9 pin is released from its respotter unit i I and reset on the alley. This action can be summarized as follows: The pinspotter retains the knowledge of which pins have fallen (by closing the relays 326 corresponding to the standing pins) from the instant the table descends after a ball is delivered until a very short time before the table descends after the next delivery.

By the action described above pin light No. 9 is on and relay NM is energized indicating that this is a non-mark ball. Also, all contacts 32511 are closed except that corresponding to pin No. 9. Also, by the action described above, alley sequence wheel W0 starts to rotate. The operation of the totalizing and scoring mechanism in 19 totalizing and scoring the pin fall results of the first frame are now completed as cam 98 rotates and passes each contact WI, W2, etc., and momentarily closes or opens each contact is as follows:

Contacts W1 and W18.-Power is applied to contact WI which is connected to the open contact UI and to the open contact YY2 (Figure 3). Hence the circuit is not completed. Power is removed from contact WI 8 momentarily which deenergiz'es relay KK (the frameis completed) ,since SE8 is now open and hence there is no completed path from the power line through relay KK. Contact W2.No action as explained under ball 1, frame 1. Contact W3.As explained under ball 1, frame 1, power is brought to point P (Figure 3). At this point there is one branch which goes through closed contact PPI through the now closed contact SB2 through section disc H4 of player advancing mechanism III] (Figure 2) through units ratchet coil Q to ground. This momentary flow of current through coil Q advances the ratchet so that the indicator advances from to 1. There are three cams that rotate with the ratchet. The first closes al and opens a2 when Q advances from 9 to 0 and hence has no eifect in this case. The second cam momentarily opens QI at the end of the ratchet pull. This is used only for resetting purposes as will be described hereinafter. The third cam opens M and b2 when Q is on 0 but leaves M and 712 closed at all other times. In this particular instance hI and 11.2 were open up to now (since Q was on "0) and when contact W3 is closed contacts 71.! and n2 close.

In the same manner by the action described above in the successive closing of contacts W4-WIO, inclusive, Q advances from 1 to 2, and so on to 8. When, however, cam 98 closes contact WI I, power is applied to contact WI I which is connected through wire 599 to the now open contact 326d corresponding to the standing pin No. 9 (Figure 6). Hence, there is no count here, but when contact Wl2 is closed, by the action described above, Q advances from 8 to 9, and in player A scoreboard panel, the score of 9 is shown for the first frame.

With respect to contacts WI3, WM, Wit, WIS which are next closed by cam 98, the action is as explained for ball 1, frame 1. No net effect takes place. When cam 98 closes contact WIT, power is applied to contact WI'I, which is connected through the now closed contact SBS through closed contact V2 through closed contact NN through disc I24 of the player switch through coil N to ground. This advances the frame counter of the panel corresponding to bowler A from 0 to l. The frame counter shaft has two cams 69, 62 which rotate with it. Cam 60 opens contact NI momentarily at the end of each ratchet pull. It is used only for resetting purposes and is described hereinafter. Cam 62 opens contact nl and closes contact 112 when N reads 0 but closes contact RI and opens contact 11.2 at all other times. Thus as cam 98 of sequence wheel W0 passes contact Wil, contact nI changes from open to closed position and .eontact n2 changes from closed to open position.

Closing of contact W23 and opening of contact W24 have no effect, as described under ball 1, frame 1. Momentary opening of contact W 25 causes power to be momentarily removed from contact W25 which is connected through now closed contact SB! through relay coil SB through switch contact dbt to ground. Hence relay SB is deenergized and contact SBI opens. The sequence wheel W0 has now completed one revolution and contact WIB opens. This removes power from the motor 533 (Figure 3) and hence wheel W0 comes to rest. Shortly after all the lighted pin lights go out since cam Gilli on shaft 255 opens contact 913M. With the end of the cycle of pin spotter 2, cam 362 on shaft 255 has made one-half a revolution and power is applied to ZitZb instead of 352a. Also, cam 428 has made half a revolution so that the first ball light goes on. Player A scoreboard panel score indicator shows a score of 9, and frame indicator 3!! shows that the first frame is completed. All relays of the mechanism are deenergized.

Ball 1, frame 2 It is assumed that nine of the pins were knocked down. The action of the pin spotter and totalizing mechanism is substantially the same as that described above for ball 1, frame 1, except that only one of the pin relays 328 is energized. The net result is no score, no frame advance and no memory relays closed.

Ball 2, frame 2 (a spare) The action is as described under ball 2, frame 1, with one exception: No relays 328 are energized since there are no standing pins. Hence, all contacts 3260 are open and there is no power delivered to relay NM. Thus NM is not energized indicating that a mark has been made. However, relay SE is energized. Motor 50 is set into motion as explained above, and wheel W0 rotates. Cam 98 successively opens or closes the several contacts as follows: Contacts WI, WIS and W2 with no effect. The action is next applied to contact W3 through normally closed contact NMI through closed contact FFZ. At this point the circuit branches and goes to either the open contact U2 or the open contact YY2. Hence closing of contact W3 has no effect.

Contacts W i to WIZ, inclusive, are next closed in succession. Power is supplied through each contact to the now closed contacts 326d to the normally open contact NlVlt. Hence there is no score.

The action resulting from the closing of contact WI3 is as described above. There is no net effect in the scoring and totalizing operations. When contact WM is closed, power is supplied through momentary contact. This power is applied through closed contact FFS through closed contact NMA through now closed contact SE3 through N'N2 through disc N8 of the player advancing mechanism II 0 through coil T to ground. This energizes relay T Which closes contact TI which then keeps T energized through contact Hi to the power line even after Whl is opened. Power is supplied through the now closed contact T2 through disc E22 of player switch Hi3 through coil U to ground, thereby pulling relay U. This is the first example of a memory relay closing.

Closing of contact WIS is as described above. There is no net effect. The same holds for contact Wi6. Power is applied to WEB which is connected through normally closed contact FFA through closed contact NMS to the now open contact SBG. In the closing of contact WI'I, the action is the same as described under ball 2, frame 1, except that the frame counter N advances from 1 to 2. Closing of contact W23 and opening of contact W24 has no effect as described above. When contact W25 is opened, as exbe rolled (ball 1, frame 3) is the first ball after a spare. The spare light of pin spotting machine 2 is energized.

Ball 1, frame 3.

Nine pins are knocked down (say pin 10 remains standing). The initial action is as described under ball 1, frame 1. When the sequence wheel WO starts to rotate SB is not energized but NM, T and U are energized. The opening or closing of contacts Wl-W25, inclusive, is as fol lows:

Contact W1 .Power is applied through W I through the now closed contact UI through disc II6 of player switch IIO to the open contact Y5. Hence this has no effect. Contact W18.-The action is as described under ball 1, frame 1. Contact W2.--Power is applied through contact W2 to the now closed contact U2 through disc H5 of player switch I I through the normally closed switch a2 through the coil of ratchet relay Q to ground, thereby advancing the counter of this relay from 0 to 1, indicating now a score of 19.

There are three cams that rotate with the shaft of ratchet relay Q. The first closes contact a'I when the counter advances from 9 to 0 and hence has no effect in this case. The second cam momentarily opens contact Q'l at the end of the ratchet pull. This is used for resetting purposes and will be described hereinafter. The third cam opens contacts hI and Ir: when the counter of ratchet relay Q is on 0 but leaves contacts h'I and h'2 closed at all other times. At this particular instant, contacts h'I and 71/2 were open up to now (since Q was on "0), and when contact W2 is made contacts 7 and h2 close.

Contact W3.-Power is applied through contact W3 through now closed contact NMZ through wire I'1 through now closed contact 326d corresponding to pin No. 1 through now closed contact NM3 through normally closed contact FF3 through now closed contact U3 through disc lid of player switch IIO through the coil ofratchet relay Q to ground. This advances the counter of ratchet relay Q from 9 to 0.

By the action described above, when the counter of relay Q advances from 9 to 0, contact a2 is momentarily opened and contact a1 is momentarily closed. This applies power from the line through contact aI through the coil of Q to ground and the counter of Q advances from 1 to 2. Hence the score now reads 20. By the action described above contact hi is open since the counter of Q reads zero.

Contact W4.Power is applied through contact W4 through wire 5 I 6 through closed contact 326d corresponding to pin 2 through now closed contact NM3 through normally closed contact FF3 through now closed contact U3 through section II4 of the player switch IIO through coil Q to ground. This advances the counter of Q from 0 to 1. The score is now 21 in player panel A at 34.

Contacts W5, W6, W1, W8, W9, WIO and WII close in succession as high portion 99 of cam 98 of wheel W0 engages the same in succession. By action similar to that described for W4, the counter of ratchet relay Q advances one step for each contact from 1 to 8 and the score of player A reads 28.

Contact W12.Power is applied through contact WI2 through wire 508 to the now open contact 326d corresponding to standing pin 10. Hence there is no action.

Contact W13.-Power is applied through contact WI 3 through disc II I of player switch IIU through coil R to ground. This momentarily opens contact RI and hence the power circuit going to coil T, thereby deenergizing relay T and also relay U. Spare light SP goes out.

Contacts WM, WI5, WIB, WII, W23, W24 and W25 are next closed or opened as wheel W0 continues its rotation and comes to a stop after opening contact W25. Action is as described under ball 1, frame 1.

To recapitulate.-The score is 28. The frame counter reads 2. No memory relays T, Y, Z or U are excited.

Ball 2, frame 3 No additional pins are knocked down. The action is similar to that described under ball 2, frame 1. The score is now advanced from 28 to 3'7. Theframe counter advances from 2 to 3, and frame 3 is completed.

Ball 1, frame 4 A strike is delivered. The initial action is as described under ball 1, frame 1 except that now all pins are knocked down and hence none of the relays 326 are energized. Hence all contacts 3260 remain open and relay NM is not energized (as a mark has been made). Also, SB is not energized since it is a first ball. Sequence wheel WO starts to rotate and the action is as follows:

Contacts W1, W18 and W2.Action is as described for ball 1, frame 1.

Contact W3.Power is applied through contact W3 through closed contact NMI through closed contact FFZ to either open contact U2 or open contact YYZ or open contact W2. Hence closing contact W3 has no effect. Contacts W4, W5, W6, W7, W8, W9, WIll, WI! and WI2 are closed in succession. I

Power is applied through each contact WlWI 2 in turn to the corresponding now closed pin contact 326d to the open contact NM3. Hence there is no score recorded. Contacts W13, W14 and W15.--'Ihe action is as described for ball 1, frame 1. No relays are set. Contact W16. Power is applied through contact WI 6 through closed contact 'FF4 through closed contact NM5 through closed contact SB4 through closed contact NN3 through section I2I of player switch I I0 through the coil of relay Y to ground. Hence,

relay Y is energized. This closes contact YI and this keeps relay Y energized even after contact WIS opens since power is applied through normally closed contact RRI through now closed contact YI through coil Y to ground. This is the first example of thesetting of the strike memory relay Y. Contact Y3 now closes and the strike light on the totalizer at 32 of player A panel is energized since power is applied through Y3 through the light to ground.

Contact W17 .-Power is applied through contact WI'I through closed contact NM'I through closed contact V2 through closed contact NN5 through section or disc I24 of player switch IIU through coil N to ground This advances th frame counter N from 3 to l. Contacts W24, W25 .Action is the same as described under ball 1, frame 1. The rest of the cycle is the same as explained under ball 1, frame 1 with one exception. The pinspotter control strike relay 359 is energized by suitable mechanism (not shown) similar in construction and operation to that shown in the above referred to Broekhuysen patent. This operates switch 3551f so that at the end of the cycle the first ball light and not the second ball light is lighted.

To recapitulate-The frame counter has advanced from 3 to *1. The score remains at 37. The strike light is lighted. The strike memory relay Y is energized to indicate that the next ball to be rolled is one ball after a strike.

7 Ball 1, frame 5 It is assumed that eight pins are knocked down (say No. '7 and No. 9 are still standing). The initial action is as described under ball 1, frame 1. Relays NM and Y are energized, whereas relay SB is not when WO starts to rotate, whereupon high portion 8% of cam 98 engages contacts W i- WIS, inclusive, W23, W24 and W25. The action set up due to the engagement of contacts W i, W I 8 and W 2-WI3, inclusive, is the same as that described under ball 1, frame 1. The remainder of the action is as follows:

Contact W14.Power is applied through contact WM through section H9 of player switch IIO through now closed contact Y2 through coil Z to ground. This energizes relay Z which closes ZI and Z is then held in by the power through normally closed contact RI through contact Zi through coil Z to ground. When contact Z2 closes power is applied through section I22 of player switch IIB through coil U to ground, thereby energizing relay U. When contact Z3 closes power is applied to the second strike light so that it goes on.

Contact W15.Pwer is applied through contact W I through section i26 of player switch III through coil RR to ground. This energizes relay RR momentarily and hence normally closed contact ER! is momentarily opened. This breaks the circuit which delivered power through contacts RRI and Y! to relay Y which is deenergized, opening contact YI and hence relay Y remains deenergized even after contact RR! closes again. Contact Y3 returns to its normally open position and the first strike light goes out.

Contacts WIS, WI'I, W24 and W25 when closed or opened by cam 98 efiect the operations as d scribed under ball 1, frame 1. The remainder-of this cycle is the same as described under ball 1, frame 1.

To recapituZa'te.- The score remains at 37. The frame count remains at 4. The first strike light goes out and the second strike light goes on (this indicates that there is one more ball to be bowled before the strike can be scored). The relays Z and U are energized indicating that the next ball to be delivered is the second ball after a strike.

Ball 2, frame 5 ContactWZZ-PoWer'is' appliedthrough contact 24 W2 through now closed contact U2 through section I iii of player switch I Ill, through closed contact a2 through the coil of ratchet relay Q to ground. Hence the ratchet Q advances the counter from 2-3 to a (indicating a score of 47 at this instant Power is also applied through contact W2 through now closed contact U2 through now closed contacts NMS and SE5 and through normally contact NN'i through coil V to ground. This energizes relay V which closes contact VI. Since contact W is is closed, power is now applied from the line through WIS through now closed contact VI through coil V to ground which thus keeps relay V energized.

This is the first time relay V has been energized. Its action in causing a second rotation of the sequence wheel will be described hereinafter.

Contacts W3 tit-rough W12.'1he action is as described under ball 2, frame 1. Nine more points are scored so that the scoreboard now indicates 55 (this is exactly the score that an ofiicial scorekeeper would place in box 4 of the chart described hereinabove) I Contact W13.Power is applied through con tact W I3 through section II! of player switch I Ill through coil R to ground momentarily, theremomentarily opening contact RI. Since power is supplied to relay Z through contacts RI and Z3 then when RI opens momentarily relay Z is deenergized and ZI opens so that even after Rt closes again relay Z remains deenergized. This opens contact Z2 which deenergizes relay U since the power was supplied to this relay through Z2 through section I22 of player switch IID. Contact Z3 also opens and the second strike light is extinguished.

Contact W14.The action of this contact is the same as described under ball 1, frame 1.

Contacts W15 and W16.-The action is as described under ball 2, frame 1.

Contact W17.-Power is applied through contact WI'I through now closed contact SE8 to now open contact V2. Hence, there is no closed circuit to frame counter N and the frame count remains at 4 for the moment.

Contacts W23 and W24.l-lo action, as described under ball 2, frame 1.

Contact W25.Note that power is applied from the power line through normally closed contact W25 through now closed contact SB! through relay coil SB through normally closed contact db i to ground. Hence, even when the power is momentarily removed from W25 (which normally feeds relay SB through contact SBI) the relay SE is not deenergized.

The wheel W0 now has made one complete revolution and contact W Il now opens. How

ever, this does not now remove power from the sequence wheel motor 50 because contact V3 is now closed and thus shunts Wis. Thus power is supplied through now closed contact V3 through motor 50 to ground. Hence the sequence wheel W 0 starts on its second rotation.

Contact W18.Since power is applied through contact W18 through hold-in coil VI, through coil V to ground when W H3 is momentarily opened, relay V is deenergized and stays deenergized. This opens contact V3 but this does not stop the rotation of the sequence wheel because before cam 98 of wheel WO' reached contact WI 8, cam I00 of the wheel has already closed contact W 59 through which power. is supplied to motor 50;
